Phytochemical screening and metal binding studies on floral extract of Solanum nigrum

Abstract

Traditional medicine involves the use of different bioactive constituents present in medicinal plants. The present study was carried out on preliminary phytochemicals, metal binding capacity and on floral extract of Solanum nigrum plant. The alcoholic extract was tested for the presence of alkaloids, flavanoids, tannins, phenol, saponins, steroids, glycosides, quinones and coumarins. The UV–VIS spectrum analysis was done to study metal binding capacity of floral extract of Solanum nigrum with different metal chlorides. For this comparative study is done by measuring absorption intensities of the extract, metal chlorides and mixture of extract – metal chloride at wavelength ranging from 200 to 800 nm. Phytochemical screening highlighted the presence of flavanoids, tannins, phenol, steroids, glycosides, quinones and coumarins bioactive constituents in Solanum nigrum which can be used for further investigation of bioactive compounds. UV absorption studies showed the binding potential of floral extract of Solanum nigrum with various metal chlorides.
